Brooke Moore, MSc<\/p>\nEuropean summers are getting too hot for medicines. As heat waves routinely push past 40 \u00b0C across the continent, storage and delivery facilities, older clinics and pharmacies, and patients in their homes are struggling to keep temperature-sensitive drugs from degrading.<\/p>\n
\u201cThe vast majority of European healthcare facilities were built for a climate that no longer exists,\u201d Erik Ruiz, MSc, safer pharma programme manager at Health Care Without Harm Europe, told Medscape News Europe. \u201cFor decades, Europe\u2019s hospitals were designed around a baseline of mild summers and predictable weather, utilizing materials and layouts optimized to retain warmth rather than reject it. Today, as relentless heat waves, severe flash floods, and unprecedented storms become the norm across the continent, these structures are transforming into operational liabilities.\u201d<\/p>\n
Many modern medicines, including insulin, advanced biologics, and mRNA vaccines, depend on a rigid, temperature-controlled cold chain that must be strictly maintained between 2 \u00b0C and 8 \u00b0C. Yet a vast network of older healthcare facilities across Europe lacks the high-specification, integrated heating, ventilation, and air conditioning systems required to regulate thermal comfort, manage humidity, and guarantee stable indoor air quality when outdoor ambient temperatures soar.<\/p>\n
The financial toll of this infrastructure deficit is immediate, said Brooke Moore, MSc, a policy analyst in the Sustainable Prosperity for Europe Programme at the European Policy Centre. She added that failure to adapt is costing time, money, or effort that cannot be recovered. \u201cWhen these medications are damaged, or they\u2019re no longer viable or usable, that is a sunk cost.\u201d<\/p>\n
From Centralized Security to Household Gaps<\/p>\n
A spokesperson from the European Commission said that the Commission and its Health Emergency Preparedness and Response Authority are working on protecting macro-warehouses by stress-testing storage facilities and routinely conducting field inspections of national stockpiles to ensure they can survive extreme heat. However, securing the final mile of medicine delivery remains highly volatile. Once a shipment leaves these heavily monitored hubs, the safety net thins drastically.<\/p>\n

Moore said that the conversation around climate adaptation also frequently ignores what happens in patients\u2019 homes. \u201cWe speak about pharmaceutical companies and healthcare providers needing to be the ones to adapt, but of course when we talk about things like insulin, the conversation should include people in their households,\u201d she said.<\/p>\n
Thermal degradation of a medicine can be completely invisible. \u201cThe challenge is that many patients wouldn\u2019t even know if their medicines have been compromised or degraded. Greater communication around this should get the public\u2019s attention,\u201d Moore said.<\/p>\n
